CAN-END CLOSURE.

Specification of Letters Patent,

Application filed October 17, 1912. Serial No. 726,854.

To all wh om it may concern I Be it known that 1, JOHN M. YOUNG, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Can-End Closures, of which the following is a specification.

The hereinafter described invention relates to the lining of what is known to the trade as sanitary or double seaming can ends, that is, such ends the seaming flange of which are lined with some form of a p'acki in order that when the ends are applie to the can body by a double seaming, rtight joint or hermetical seal is formed without the use of solder. a

'The object of the invention is to make it practical to use a fibrous liner, preferably ape'r, and apply the same to the flange of he can end before the. end is united to the can body and to so secure the same in'position relative to the flange of the canend as to remove the danger of the liner'ring falling off and becoming detached from theflange of-the can end while beingyhandled before or during the time of applying the end to the can body, or while the end with the fibrous liner applied thereto is being shipped from the factory to the cannery or canning establishment where it is to be applied to the open end of the can after the same has been filled with the food product. Heretofore fibrous liners or liner rings have been secured to the flange of the can end by pasting\ or gluing the same thereto t e end being applied to the end of the can body for the dou lo seaming thereof, but at best such is only an insecure method of securing the liners or liner rings to the fiangle handlin t ereof by the workmen or operators ten s to damage, tear or injure the liner ring to such an extent as to cause an imperfect seal to be formed when the can end is double seamed onto the can body and thereby causes a leaky joint. For the formation of a perfect hermetically sealed joint 1t 1s essential that the liner or liner ring applied to the flange of the can end he not marred or fall off, else the closing machine for double seaming the flange of the can end to the can body Wlll make an imperfectly closed joint for the can.

' should be fibrous ring of, said view illustrating the edge of th ring liner 6 and the flan of the can end, inasmuch as the To comprehend-the invention, reference ad to the accompanying sheet of drawings, wherein v f Figure 1 is a side view of a can partly broken away withthe end cover and ring liner applied thereto. Fig. 2 is a bottom plan new of a can end cover with the brous ring liner positioned relative to the flange of the can end. Fig; 3 is a cross sec: tional view of the can end cover with, the liner united to the flange there flan e of the endcover as curled inwardly to hol the ring liner'in lace.

In the drawings, t numeral 1 isused to desi ate any suitable form ofa metallic can bc y, and 2 the end covers or can ends united thereto by the usual double seam joint. The can end covers are preferably Patented June 16, 1914..

formed with a depressed channel 3'and an upraised central portion 4;, and an outwardly projecting flange 5 extended from the end in -a plane above that of the'centra-l portion thereof, and to the under face iof which in any suitable mam-\enj'a flange is applied,

preferably torment! fibrous ring liner 6,

aper. inturning or our ing the outer ed e of the flange 5, as shown at 7,Fig. 3 of t he draw.-. ings, so that the ring liner, is held within an annular groove 8 in the under face of the can end against displacement'du'rin the rough handling and usage to which tie ends are subjected in canning establishments.

the en e can body, the openend of the said body hen united tothe 0 ends of the can.

This rin liner 6 is held in placebys In agplyingl the can end or end covers to v s of t is forced against the fibrous of the can end end 0 the can bod y .by v the usual double seaming process, which rolls 'or folds the lined flange of the can end to' "producing a hermett the employment of a fibrous or paper'loo ring liner for the flange of the can end there is provided-a yielding seat against which the end-of the can is orced during the operation of applying the ends thereto, which ring liner readily rolls or folds during the process of double seaming the flange of the end to the end of the can body and by so doing completely fills the joint so formed,

and this without any danger of the ring liner breaking or cracking during the formation of the end joint, and when the joint is formed and the seal made, there is no impure material'to be acted on by the eontents of the can. i

t The advantages of applying the fibrous or paper ring as abovedescribed, to the inn der laee of the can end llange to fill the joint union when the end is secured to the can body, are a better and more ellicient joint union'or closure joint is formed; the providing 01 :1 non-leak v joint; disposing,' of the danger of the ring' liner breaking away from the can end flange to which it is applied; the liner ring does not become displaced during the handling to which the ends are subjected; and finally it is applied at a less cost than the een'ient, plastic and composite linings for the can end flange and materially reduees the expense incident to the end joint of the cans, while at the same time providing an absolute hernn-tieally sealed sanitary joint} By thus uniting or securing the ring liner in place by curling or 'inttu'ning the end oi the llange of the can end, the ends may be lined at the can mak- 'ing factory and the lined ends shipped to the carn'iii'ig establishment in a eoudit ion for double seaming to the can body, with the I assurance that the ring hner or fibrous pack-- ing will not become loosened or marred duringhandling. This is a decided ad 'antage over-the requirement that the ring liners be applied by hand as the end is about to be secured to the can body, for as stated, such handling of the delicate fibrous ring liners f tends to injure the same and to cause the formation of an imperfect 0r lealty joint.

Having thus described the invention what is claimed as new and desired to protect by Letters latent is:-

1. A can end for the closure of sanitary (-ans having an outwardly projecting flange for the seaming thereof to the end of a can body, and a rut fibrous ritre liner applied to the inner l'aee of the run end flange and adapted'to interlold with the said llange and the end of a can body during the seaming thereof to provide a sanitary paelin for the end joint of the can, said liner being held in position relative to the (an end b v inturning or curling the llange oi the end to embrace or inelose a portion of said liner.

2. can end provided with an outwardly projected cireuinferential tlan e'e, an integral fibrous ring liner secured to said end, said liner being held in plate relative thereto b inturning the eirr-uml'erential edge of the flange to partly embrace the liner ring".

3. The, combination with a can end provided with a eireuml'erential flange ha\in its edge inturned to forin an annular groove or hannel, of a cut paper ring liner tilted onto aid eirrutnferential llans' e and held in position relative thereto by the inturned edge ol the said flangev In testimony whereof I have signed my name to this specification in the presence of two substribintr witnesses.
